Papers by Keyword: Stress Induced Grain Growth

Abstract: We suggest a simple method to study the mechanical behaviour of nanocrystalline (nc)
samples in compression-torsion mode. High applied pressure prevents the fracture of sample, and
quantitative parameters of sample response during torsion test can be compared with developed
microstructure. Here we present and discuss the results of systematic investigation of mechanical
behaviour of nc Pd with a mean grain size of 12 nm in a wide range of shear strains (0
